mysql循环语句的例子：Repeat until loop

分享下mysql中unitl循环的用法实例，供大家参考。

代码如下：

mysql> delimiter //
mysql> create procedure test_repeat (IN in_count INT) //创建一个mysql存储过程
    -> BEGIN
    ->     declare count INT default 0;
    ->
    ->     increment: repeat
    ->         set count = count + 1;
    ->         select count;
    ->         until count > 10
    ->     end repeat increment;
    ->
    -> END
    -> //
Query OK, 0 rows affected (0.00 sec)

mysql> delimiter ;
mysql> call test_repeat(10); //调用mysql存储过程
